I am pretty new at this x carve but here is a sign I made.
I want to pay a huge shout out the the folks from Inventables for their outstanding customer service!
I had completed about 5 jobs when the machine went off coarse. It broke my bit and did it again a few days later. I am not sure what exactly happened but the second time it happened the X belt broke. I called and told them what had happened and they sent out two new bits and enough belt to re-belt at least two more times.
since then it has been working with no issues. I re-calibrated and double checked for any loose parts.
I am so glad I choose Inventables!
